Your benefits

Hygienic working environment
The stainless steel gearmotors have an easy-to-clean surface structure.

Compact installation
The KES.. helical-bevel gearmotor and the WES.. SPIROPLAN® gearmotors are been specifically designed with a directly mounted right-angle gear unit that saves on space.

Smooth production
Our RES.., KES.. and WES.. asynchronous stainless steel gearmotors are durably constructed.

Hygiene as a priority: Optimized efficiency and low maintenance with long service life

Do you have particularly high demands in terms of hygiene and easy cleaning? We offer you the ideal drive solution for hygiene-sensitive areas requiring intensive cleaning.

The RES.., KES.. and WES.. asynchronous stainless steel gearmotors are constructed in such a way that their surfaces are particularly easy to clean. The housing is constructed entirely from high-quality stainless steel. The surface was designed to systematically prevent the occurrence of indentations and potential dirt traps, making it easy to clean. The fanless design also ensures exemplary hygiene as it prevents swirls of dust and dirt.

The small and compact design of our RES.., KES.. and WES.. asynchronous stainless steel gearmotors means they can be used for a variety of sensitive hygiene applications – for example, in the food and beverage industry or the pharmaceutical industry. Thanks to their design, these gearmotors are low-maintenance and have a long service life. In addition to this, the high-quality stainless steel design protects them against corrosion and provides them with high-grade resistance to acid and alkaline. Due to their optimized efficiency, these gearmotors are also particularly cost-effective and can achieve torques of up to 600 Nm.

In addition to the asynchronous stainless steel motors, our stainless steel servomotors from the CM2H.. series can also be attached to the stainless steel gear units using adapters. This results in an energy-saving belt drive for hygienic or cleaning-intensive areas, for example.
